In recent applications of zinc nickel (ZnNi) its excellent resistance to corrosion is not only its standout feature, it also offers an important advantage that enhances its overall value. This alloy demonstrates higher corrosion protection compared to traditional zinc coatings. In addition to slowing down corrosion generally, zinc nickel also tends to corrode only on the surface. This prevents the deep and extensive corrosion often observed in zinc coatings.
